24
Q

Volunteer Sample-Weaknesses

A
  • Volunteer bias-a certain type of person may be attracted-affects generalisation
  • Partcipants may refuse to participate
25
Q

Naturalistic Observation-Strength

A

-High ecological validity as behaviour occurs naturally in its natural environment-Easy to generalize

26
Q

Naturalistic Observations-Weaknessess

A
  • Hard to replicate-Lack of control

- Uncontrolled Extraneous Variables

27
Q

Controlled Observations-Strengths

A
  • Replicable- Highly controlled

- Extraneous Variables have little effect

28
Q

Controlled Observation-Weakness

A

-Findings cannot be generalised

29
Q

Covert Observation-Strength

A

-All natural behaviour is on show as the participants don’t know that they are being observed-Increases the validity

30
Q

Covert Observation-Weakness

A

-Ethical issues- Privacy and Consent

31
Q

Overt Observation-Strength

A

-Less ethical issues-Partcipants know they are being observed

32
Q

Overt Observation-Weakness

A

-As they know that they are being observed-Demand Characteristics and Non natural behaviour could occur

33
Q

Structured Observation-Strengths

A
  • Easy to record behaviour-Uses behavioural categories

- Produces Quantitative Data-Easy to analyse

34
Q

Structured Observation-Weaknesses

A

-Less detailed results

35
Q

Unstructured Observation-Strength

A

-Infomation is more detailed

36
Q

Unstructured Observation-Weaknesses

A
  • Provides qualitative data-harder to analyse

- High chance of observer bias-they pick behaviour to analyse-No behaviour categories

37
Q

Event Sampling-Strength

A

-Useful when the event frequently occurs

38
Q

Event Sampling-Weakness

A

-Observer may overlook details and behaviours if they are too complex

39
Q

Time Sampling-Strength

A

-Reduces the number of investigations that have to occur

40
Q

Time Sampling-Weakness

A

-An observed behaviour may unrepresentative of the investigation as a whole

41
Q

Questionnaires-Strengths

A
  • Cost effective
  • Can be completed without a researcher
  • Quantitative data produced-Easy to analyse and compare
42
Q

Questionnaires-Weaknesses

A
  • Social Desirability Bias-People could lie to be more socially desirable

43
Q

  • Straightforward and easy to replicate

- Data is easy to analyse

44
Q

Structured Interview-Weaknesses

A

-Interviewer cannot deviate from the set of questions-this annoys and frustrates them

A

-More flexibility-follow up questions can be asked

46
Q

Unstructured Interview-Weaknesses

A
  • Data is harder to analyse

- People may lie on their responses-Social desirability bias

47

Correlations-Strengths

A
  • Can be used as a preliminary tool or as a starting point for research
  • Quick and economical
  • Can use secondary data
48
Q

Correlations-Weaknesses

A
  • Can only tell us how variables are related, but not why

- “Third-Variable Problem”-a untested variable affecting one or both co-variables

49
Q

Qualitative Data-Strengths

A
  • More detail

- More external validity- provides researchers with participants insight

50
Q

Qualitative Data-Weaknesses

A
  • Harder to analyse
  • Patterns can be hard to identify
  • Conclusions are based on subjective interpretation
51
Q

Quantitative Data-Strengths

A
  • Simple to analyse
  • Easy to find patterns
  • More objective
52
Q

Quantitative Data-Weaknesses

A
  • Narrower- less detail

- Fails to represent “real-life”

53
Q

Primary Data-Strengths

A
  • Obtained from the participants themselves

- Collected in multiple ways

54
Q

Primary Data-Weakness

A

-Requires time and effort to produce data as experiment has to be done

55
Q

Secondary Data-Strengths

A
  • Inexpensive and quick to access

- Might be no need to conduct a study as data might be enough

56
Q

Secondary Data-Weaknesse

A

-Large variation of quantity of secondary data- it could be out-dated or have many flaws

57
Q

Peer Review-Strengths

A
  • Established validity in the research

- Makes sure research is accurate

58
Q

Peer Review-Weaknesses

A
  • Anomity-Other can use it as a chance to get revenge on someone
  • Publication Bias- journals only publish works that they like- creates a false impression of the state of psychology
  • Burying ground-breaking research-they try to maintain the status-quo within certain areas
